[QUOTE="WalnLiz, post: 111948, member: 147"] My advice is per the PM you sent me, but hopefully some of the Lapidary guys may have some suggestions for you. A Refractive Index test is what I would certainly do first to at least get it into a specific gemstone group. Some pics with direct natural sunlight would give us a better indication of colour and possible colour change on Axis rotation. Cheers Wal. [/QUOTE]
